AI Technical Summary

Benefits of technology

The system provides lightweight, scalable ballistic protection capable of defeating Armor Piercing and Armor Piercing Incendiary rounds, with improved hardness and energy absorption, maintaining effectiveness across various applications without significant weight increase.

Problems solved by technology

The penetrator tip is caused to decelerate more rapidly than the trailing end of the bullet such that penetrator is damaged and blunted.

Embodiment Construction

[0014]Referring to FIG. 1, an armor system 30 includes an armored panel 32 which is manufactured as a layered structure having a multiple materials some of which maybe bonded together. The armored panel 32 generally includes a front face layer 38 (optional), a hard ballistic material layer 40, a compressed oriented fiber spall shield layer 42, a spacer layer 44 (optional) and a backing layer 46 (optional). In one disclosed embodiment, the front face layer 38 is approximately 0.02 inches thick, the hard ballistic material layer 40 is approximately 0.35 inches thick, the compressed oriented fiber spall shield layer 42 is approximately 0.5 inches thick, the spacer layer 44 is approximately 0.22 inches thick, and the backing layer 46 is approximately 0.09 inches thick.

[0015]The front face layer 38 and the backing layer 46 are preferably manufactured from a polymer matrix composite glass fabric cloth such as fiberglass, S-2 Glass, IM Graphite, Low Mod Graphite, Kevlar or the like which i...

Abstract

An armor system with a lightweight armored panel manufactured as a multi-material structure having a multiple of layers including a hard ballistic material layer of a Ceramic / CMC (Ceramic Matrix Composite) hybrid armor material capable of defeating ballistic threats. The monolithic ceramic layer includes a surface enhancement to the expected projectile impact face of a minimal weight yet which provides significant ballistic performance improvement.

Description

BACKGROUND OF THE INVENTION[0001]The present application is a Continuation-In-Part application of U.S. patent application Ser. No. 11 / 627,491, filed Jan. 26, 2007 (which claims the benefit of U.S. Provisional Patent Application No. 60 / 794,276, filed Apr. 20, 2006) and U.S. patent application Ser. No. 11 / 682,390, filed Mar. 6, 2007 (which claims the benefit of U.S. Provisional Patent Application No. 60 / 794,276, filed Apr. 20, 2006).[0002]The present invention relates to an armor system, and more particularly to an armor system having a multiple of layers including a hard ballistic material layer made of a Ceramic / CMC hybrid armor material with a surface enhancement.[0003]A variety of configurations of projectile-resistant armor are known. Some are used on vehicles while others are specifically intended to protect an individual. Some materials or material combinations have proven useful for both applications.[0004]Accordingly, it is desirable to provide a lightweight armor system usab...
